|
Program Manager panel |
Displays program types that support 4 channels in/out |
Gateway 8/16 |
Programs |
Supports program connections using up to 16 channels of audio, depending on codec configuration purchased (between 8 and 16 channels available for purchase) |
|
Program Manager panel |
The Gateway 8 displays program types that support 8 channels in/out; the Gateway 16 displays program types that support 16 channels in/out. |
The codec is capable of streaming phase-aligned multichannel and surround sound audio streams according to SMPTE ST 2110-30 standards. Support is available for streaming 4, 6 and 8 digital channels in phase-aligned streaming mode. It is also possible to stream 6 channels of phase-aligned audio, plus a phase-aligned stereo IP stream. This allows networks to deliver live content in both stereo and multichannel sound formats for a variety of live broadcast applications and audiences, or STL and studio-to-studio applications. The Gateway 16 also supports sending 6 + 6 + 2 + 2 channels of phase-aligned streams, or 8 + 8 channels of phase-aligned streams, or 4 + 4 + 4 + 4 channels of phase-locked streams.
Configuring Phase Locked Streaming Programs
Configuration is similar to setting up a regular connection program. In the Program Manager panel select the program with the preferred connection profile suiting a phase-locked 6 channel (5.1 or 6.0) or 8 channel (7.1 or 8.0) surround sound stream, or a 4 channel audio stream.
Gateway-16 phase locked program options
Select a preferred encoding algorithm when configuring a program using the Program Manager panel.
The following table displays the mapping of channels to encoders and decoders for 5.1 channel and 7.1 channel surround sound streams. This is based on the audio channel group order defined in the SMPTE ST 2110-30 standard. Please note: 6.0 and 8.0 channel streams feature undefined channel grouping. All channels are the same quality and are not bandwidth limited. The selection of 7.1 or 8.0, and 5.1 or 6.0, for streaming is determined when selecting the encoding algorithm when creating a program.

Codec Model Note: Only 4.0 channel phase-locked audio is supported in the Gateway 4. |
